已建堤防加固工程中对软土层的勘察和评价方法探讨

Discussion on the Methods of Investigation and Evaluation of the Soft Soil Layers in the Existing Embankment Reinforcement Project

重点论述在堤防加固工程中,软土层在老堤之下和老堤之外的物理力学性质的差异,指出由此造成的新筑堤身失稳原理,提出针对堤防加固工程的勘察应该充分考虑到已建堤防对堤基土体的作用影响。

In the paper, the authors mainly discuss the differences of physical and mechanical properties of the soft soil layers beneath and outside of the old embankment in its reinforcement project, and further indicate the principle of new built embankment instability resulting from the differences. Accordingly, in the investigation process, the effect of the existing embankment on the soil mass in the dam foundation must be fully taken into account.
